Grinding assembly of a pepper grinder

Abstract

A grinding assembly of a pepper grinder has an inner and an outer grinding members. The inner grinding member is turnably received in the outer member. The inner member has grinding teeth on an outer side thereof, opposing grinding teeth of an inner side of the outer member. The inner member grinding teeth are not in touch with the outer member grinding teeth. The inner member further has a lower end annular part touching lower ends of the outer member grinding teeth. Because the grinding teeth do not touch each other, the inner grinding member can be turned more smoothly.

What is claimed is:  
     
       1. A grinding assembly of a pepper grinder comprising: 
       an outer grinding member having a first through passage extending therethrough, said first through passage defining an inner surface of said outer grinding member, said inner surface having a first set of grinding teeth formed thereon;  
       an inner grinding member having a second through passage extending therethrough, said second through passage having a substantially square shaped cross-section for receiving a grinding shaft, said inner grinding member having an outer surface and a lower end, said lower end having an annular rim formed thereon, said outer surface having a plurality of guide trenches and a second set of grinding teeth formed thereon, said second set of grinding teeth forming boundaries between adjacent pairs of said guide trenches, said inner grinding member being rotatably received within said first through passage of said outer grinding member, said second set of grinding teeth being spaced apart from said first set of grinding teeth, said annular rim contiguous said first set of grinding teeth, whereby said inner surface of said outer grinding member, said outer surface of said inner grinding member, and said annular rim form a cavity for grinding pepper between said first and second sets of grinding teeth when said shaft is rotated.
